A country is big if it has an area of bigger than 3 million square km or a population of more than 25 million.

Write a SQL solution to output big countries' name, population and area.

For example, according to the above table, we should output:

name population area
Afghanistan 25500100 652230
Algeria 37100000 2381741
SELECT NAME, POPULATION, AREA
FROM World
WHERE area > 3000000 OR
              POPULATION > 25000000;
